Many thanks for your email. I understand your concern, this is also a concern of mine. The only reason why there is not a git repository yet is because the code is not mature enough for community collaborations. It is evolving too rapidly and the best thing to do would be to wait until we have a stable version (1.0.0, and by stable I mean a code that is not going to change drastically after that but will be ready for fixes and inclusion of new methods). More than being helpful, putting the sources on a repo now would make the community very confused as the code is changing on an hour basis..
In any case, this doesn't stop collaborations since there are already many of them happening right now but by email (again, only because the code is not at its stable version). As soon as Gneural Network will have its structure very well defined, and therefore ready for community development, of course there will be a git repository. Hopefully, this will happen in less than a month. Please, bare in mind that there is A LOT going on right now behind the scene, it is a lot of work being developed at very rapid rate and I am doing my best to make it happen quickly. Actually, I can't wait for you guys to have this first stable version on a git repo!
Please, don't get me wrong. I am very happy about your comment. It shows interest from you and this community and this is VERY encouraging and pushing me to release version 1.0.0 as soon as I can! ;)
